ADJUSTMENTS
In case that some asymmetry of braking
between the left and right brake occurs
after such adjustment, it is necessary to
release the adjustment screw (7) of that
brake that brakes more intensively up to
the moment when braking effects of both
wheels are balanced; however, it is al-
lowed to release the screw max. by 1/2
of turn. In case that even after this read-
justment the asymmetry of braking con-
tinues, it is necessary to adjust the
brakes of the tractor in an authorised re-
pair shop.
ADJUSTMENT OF HAND BRAKE
1. Adjust the lever (4) so that the dis-
tance between the bracket (K) and
face of the fork on the lever (4) is
109mm (the lever (4) should form an
angle 20° with vertical plane).
2. Screw in the nut (2) onto the contact
surface of the pin (3) without any play
and pre-stress – the arms (5) shall not
be squeezed.
3. The adjustment procedure is identical
for the right and left sides of the trac-
tor.
4. Using the nuts (8) adjust the hand
brake lever Bowden so that at angle
20° on the lever (4) the hand brake
lever is without any play.
5. Lift and lower the hand brake lever (1)
several times to eliminated any possi-
ble plays between the components.
6. Check adjustment of the hand brake
system and if necessary, correct the
adjustment and check tightening of all
locking nuts (6), (8).
In case that some asymmetry of hand
brake effect between the left and right
brake occurs after such adjustment, it is
necessary to release the adjustment nut
(2) of that brake that brakes more inten-
sively up to the moment when braking ef-
fects of both wheels are balanced; how-
ever, it is allowed to release the nut (2)
by 1.5 of turn. In case that even after this
readjustment the asymmetry of braking
continues, it is necessary to adjust the
brakes of the tractor in an authorised re-
pair shop.
Note: Adjustment holes are on the floor
of the tractor cabin to facilitate adjust-
ment of the brakes.
C754
ADJUSTMENT OF FREE TRAVEL OF
BRAKE PEDALS
Correct play between the piston rod of
brake pedal and the piston of main brake
valve is 0,5-1,0 mm (3 - 6 mm when
measured at the edge of the brake ped-
als at unlatched pedals). Adjust the play
at unlatched pedals and after releasing
of the adjusting nut (1), in which the pis-
ton rod is screwed.
